Using the Code Domain Analyzer
The code domain analyzer graphically displays the power, phase, and
timing of the CDMA signal’s 64 Walsh channels. It is a correlated
measurement, requiring an external timing signal, such as the even
second clock or the 16 × chip (19.6608 MHz) clock, to initiate a valid
measurement.
Selecting the Code Domain Analyzer’s Controls Menus
Several levels of menus are used to access the various controls
associated with the code domain analyzer. "Control Fields for CDMA
Measurements" on page 93 provides a description for each field on the
code domain analyzer’s menus. See "CDMA Measurements" on page 82
and the HP 8935 CDMA Base Station Tests Applications Guide for more
information about code domain measurements.
